My ninth observation. Probably something closer to the person who is behind the magical keyboard having duplicates. I was just thinking how difficult it must be to have multiple personalities - sometime to behave like gals (just like a thread in the Trivia folder) or to behave like a gambler using multiple gambling nicks to being a PAP supporter (aka Kinana) to a pro opposition members.
I am sure that its a matter of time the person behind the keyboard will have split personality persona disease...
To add on...Multiple personality disorder is real but it is now called Dissociative Identity disorder. (Because the psychiatrists could not agree on what exactly a "personality " is.)
Dissociative identity disorder is not genetic but is a consequence of abuse in childhood. Severe childhood abuse is relativly rare and not every case of it produces dissociative identity disorder. Also people with DID can sometimes function very well in the world, particularly if they can present only a limited professional identity. I worked with one woman who fell apart and ended up in a psych hospital only after she reached mandatory retirement age and had to leave her clerical job for a government agency. Her whole healthy persona was tied up in her work.
Dissociative experiences are not rare at all. Most people experience them. But dissociative disorders exist on a broad spectrum. The most common dissociative mental experiences are types of "defense mechanisms" by which our minds defend against unpleasent experiences. If you have ever driven somewhere and realized that you had little memory of the trip, you have dissociated. Your mind defended you against boredom by dissociating your consciousness from the process of driving.
